MACHINE FOR SETTING- EYELE'I'S AND THE LIKE.

Application filed April 7, 1919. Serial No. 288,076..

To ZZ 'whom t may concertar.'

Be it known that Bonnin' SMITH, late of Stoughton, in the county ofNorfolk and State of Massachusetts, deceased, invented certainimprovements in Machines for tietting Eyelets and the'like, of which the.following description, in connection with .the accompanying drawings,is a specification, like reference characters on the drawings indicatinglike parts in the several figures.

This invention relates to fastener-inserting` machines such as thoseused for inserting and clenching eyelets, lacing-hooks and gromets, andan important object, generally stated, is to provide an improved machinepf general utility capable of operating satisfactorily on certainspecial kinds of work that require different treatment .from thatrequired by the morecominon kinds of work.

The setting of eyelets and grornets in articles such as canvascartridge-belts for eX- ample, involves difficulties that are notencountered with the more common kinds of work such as shoe uppers andcorsets. The canvas of which cartridge-belts, machinegun-belts,haversacks, and other articles used for military purposes, is relativelythick and tightly woven. When setting fasteners in articlesmade of wovenmaterial it is not feasible to cut or punch out portions of the fabricto form the holes in which the fasteners are to be set, for the reasonthat such cutting or punching would sever the woven strands and thefabric would thereafter pull away from the fasteners and thus lose thereinforcing effect of the latter.

For this reason it is customary to form thek hole in the fabric byspreading the int-erwoven strands sufficiently to form the holes for thefasteners. It has been found, however, that the sharply pointed punchesused for this purpose become so tightly embraced bv any relatively heavyand tigl'itly woven fabric that the latter becomes distorted inconsequence of accidental edgewise displaceyment and skewed bytwistingof the punch incidentally to feeding the work. In order,therefore, to avoid these objectionable results the present inventionprovides iniproved mechanism which, in the illustrated embodiment,comprises a swivel punch, that is to say, a punch that is free to turnrelatively toits carrier, the freedom of the punch'soto turnenabling thepunch to reinain in fixed relation to the work in the event that thelatter should be twisted relatively to the punchcarrier or in the eventthat'the punch-carrier should execute angular motion relatively to thework while feed-V ing it. i lt may also be desirable and advantageous insome cases to render the clenching tool capableof'turning about its axisrelatively to its carrier, and when, asin the illustrated machine, theclenching elementA and the punch areintegral parts of the same tool theywould both be capable Vof turning as specified. The invention thereforecomprises the feature of a clenching tool constructedland arranged toturn about .its axis relatively to its carrier while the machine is incondition for use. d Y.

Another object Aof the invention is to adapt, for special work of thekind hereinbefore mentioned,- machines of otherwisewell-knownconstruction designed for operating upony Cartridgebelts, for example,may. require two, three,

the more common kinds of work.`

the latter that, when-f it is attempted to setthe fasteners at arelatively great distance from an edge of the work, the latterinterferes with the i'aceway and with the fasteners therein. This notonly displaces the work from the desired position but thel work ob-`structs the flow'of fasteners in the raceway.

ln order to avoid such interference the invention provides meansarranged to deflect upwardly that marginal portion of the work thatwould normally touch the raceway, and to support such portion above theraceway. rllheraceway is thus enabled to be reciprocated horizontallyasusual without agitating the work and without subjecting the of thework.

fasteners therein to interference on the part ln consequence of thisfeature of the invention there is a tendency on the part of the work todeviate from a straight path of feeding motion, and accordingly anotherobject is to provide means to counteract this tendency. ln thisconnection a feature of the invention consists in a worleguide arrangedto control the edge ofthe work opposite to the one that is deflected asaforesaid.

@ther features of the invention are hereinafter described and claimed,and are illustra'ted by the drawings. For convenience in illustratingthe invention, but without imposing any undue limitation thereon, thevarious features are illustrated as being' embodied in afastener-inserting machine of the same general type as that shown anddescribed in United -States Letters Patent No.

1,205,277, granted November 2]., 1916, upon anapplication of WV alterShaw. Excepting as hereinafter specified it is to be understood that themachine shown and described herein is similar to that shown anddescribed in the aforesaid patent.

Fig. 5 represents a sectional view in a vertical plane showing thesetting members completing the settinv operation; and AFig. 6 representsa perspective view of a fragment of the work-supporting' table includingtwo separable plates arranged to co-operate with the punch. K,

The upper setting` nie'rnber of the fastener-inserting mechanism isindicated at 10, and the lowersetting member is indicated vat l2. Thepunch for forming a hole in the work to receive a fastener is indicatedat i4 and, in the present instance,'is an integral part of the setting'member l0. This construction is commonly termed a combined punch andset. The punch 14E, in the present instance, is pointed so as to formthe hole by spreading the stock instead of ratones center the fastener'relatively to the setting members.

The lower` setting member is aiiiXed to a plunger i8 and the latter isarranged to slide up and down in guides one of which is indicated at 2Gin Fig. i.- A cam roll 22 carried by the plungerl co-acts with a cam 2ito movie the plunger up and down. rlChe cam is fixed to a driven shaft26 and the latter is arranged to rotate in suitable bearings in theframe 28 of the machine.

The upper setting member is carried by a carrier 30 which, in thepresent instance, is a lever. A sleeve 32 is inserted in 'the carrier tohold the setting member, and is provided with external screw-threads 34which engage internal screw-threads formed in the carrier. rlhe sleevemay, therefore, be adjusted up and down relativelyto the carrier byturning it. rllhe lower end of the sleeve is reduced in diameter and isprovided with external screw-threads r36 to coact with a binding nut 38.The carrier is bored and tapped to receive a set screw 40, the latterbeing arranged to engage a smooth rportion of the sleeve to prevent thelatter.

from turning while the nut 38 is being tightened. rlhe setting memberl0' is formed to turn relatively to the sleeve 32, and its upper end isprovided with a head 42 arranged to rest upon the upper end of thesleeve. A. screw plug del is screwed into the carrier above the settingmember to bear against the upper surface of the head 4:2

so as to sustain the stress incidental toy clenching a fastener. lnpractice the plug id will be adjusted to take up substantially all lostmotion between the setting' member and the carrier without, however,binding the setting member so as to interfere with its freedom to turnrelatively to the sleeve. The plug all. is provided with a bindnrt i6 bywhich it may be held in the desired position of adjustment.

The carrier 3() is arranged to rock upon a fulcrum member 418 the axisof which is substantially horir/iontal.l This fulcrum member en'. y oneof which is indicated at 50, this construction being` shown in theaforesaid ,patent. The blocks 50 are mortised into a forked portion atthe upper end of a post 52, the axis of which is substantially vertical.The post is arranged to turn about 4its airis in bearing 5iin the frame28, and is provided with an arm 56 by which it may be oscillated toimpart feeding motion to the carrier 30. The feeding motion is derivedy.nds through two sliding blocks from a cani 58 carried by the shaft 26and is transmitted by a cam-lever 60, rock shaft' $2, arm Gil. and links66 and 68. The two links and a third link, indicated at 70, areconnected by a common pivot member 72, and are adapted to be adjusted insuch manner as to vary the ent-ent of motion transmitted to the arm 56.

The up-and-down motion oi the settingmember is derived from a cam il.and is tr nsmitted by a vertically movable plunger To to the rear endofthe carrier 30. The upper end of the plunger is provided withhorizontal parallel members 78, 'i' 8 that form a yoke, the ends of themembers being connect-ed by rods 80. The connection between the yoke andthe rear end of the carrier emn bodies a ball-and-socket construction.the ball member 82 being iixed to the carrier. and the socket members 8dbeing disposed between the ball and the membersV 'i8 respectively. Thesocket members are provided with rollers 86, and the latter are arrangedto move in grooves 88 formed in the members T8, the grooves being curvedto impart a. slight longitudinal movement to the carrier in consequenceot the feeding motion imparted to the carrier. rlfhe carrier thus causedto execute a compound motion1 the result of which is to move thesett-ing member 10 in a straight line.

The machine is provided with a stationary work supporting table 90which, for the purpose of supporting` relatively long ar icles such ascartridge-belts, is preferably extend-- ed a considerable distance tothe right and lef-tot' the setting members. 1n the vicinity olf thesetting members the work table is eut away to receive a pair ofcooperative pla-tes 92. 92. and is provided with undercut grooves toreceive tongues 9d formed on opposite edges of the plates. rIhe platesare thus mortised into thetable and are capable of sliding; relativelyto the table and relatively to each other in lines transverseto thelines of feeding movement of the work. The plates are normally drawntoward each other by a spring 9G, the ends of which are anchoredrespectively to pins 98 carried by the plates. These-` pins extenddownwardly from the plates through slot-s 100 formed in the table. Theabuttingedges of the plates are beveled as shown by Fig. 6 to facilitatethe insertion olE the punch between them. The plates are adjustedinitially by stop members 102 clamped to the under side ot the table 90in position to engage the pins 08. rl`he stop members'are adjustablerelatively to the table, and in practice they are set at positions thatwill cause the abuttingF edoes of the plates 92 to register with thepoint orn the punch A. .When the plunger .70 at the rear of the machineis moved upwardly by its cam the punch moves downward-ly through 'thework m, and, on coming in contact with the confronting beveled ed ,ses

of the plates 92 it forces the latter apart. rlhe work .fr as shown'comprises two layers and isintended to represent the thick and' tightlywoven fabric of a cartridge-belt.l

rlhe punching motion occurs when the punch is displaced .laterally fromthe line ot the j setting member and a fastener to rpass therethrough.

Fasteners such as that indicated at a are supplied to the lower settingmember by an inclined raceway 108. This raceway, like the correspondingraceway in the aforesaid.

patent, is reciproeated horizontally toward the front and rearA of themachine in timed relation to the movements of the lower settingmembersuch that the leading fastener in the raceway will occupy a `position inregistration with the spindle 16 during the first stages ot upwardmovement of the plunger 18. The spindle 16 is thusy inserted throughthe'barrel of the leading fastener, and before the lower setting memberhas been raised far enough to engage the raceway the latter is retractedtoward the rear et the machine and is maintained out of the path of thesetting' member until the latter has subsequently descended far enoughto clear it. rlhe raceway is then movedtoward the front to present thenent fastener in the path of the spindle. The lower end ot the racewayis provided with a yielding stop by which the lea-ding;- astenerprevented rom escaping until it is withdrawn by the spindle as theraceway is retracted.

ln consequence of the inclination of the racewa-y and its close relationto the setting' members, the raceway necessarily intersects the paththat would normally be traversed by the rear edge of the work. purposesthe term work is meant to relier to the kind ot work in which thefasteners are set at a relatively great distance from the rear edge. Inorder, therefore7 to provide adequate support for the work withoutincurring interference between the table and the raceway, the rear edgeof the table is cut away toorm a notch 112 (Fig. 2) in which the racewaymoves incidentally to its reciprocating to the front andrear. This7however, does not avoid interference between the work andthe racewa-y7or the tas-` teners in the latter. ln order, therefore, to avoid suoliinterference a guard 114: is ar- For present CIK ` n Lacoste ranged inposition to hold the rear marginal portion of the work above and out ofContact with the fasteners. 1n the present instance this guard is aixedto the table and covers the notch 112. The guard is inclinedsubstantially in accordance with 'the rinclination of the raceway, beinghigher at its rear edge than at its front edge. A presserfoot 115 isarranged to depress the work against the table between the guard 114 andthe hole 106.

ln order to utilize the machine to insert two, tli-ree or four, as thecase may be, fasteners the machine is provided with two stationary butadjustable worl guides 116 and 122. 1n the present instance these guidesare c aniped to the work table, the guide 116 being provided with slots120 for the reception of clamping screws 118, and the guide 122 beingprovided with slots 124i for the reception of clamping screws 1.26. @neof these guides, preferably that at the rear of the table, is relativelynear the line in which the fasteners are inserted. When a piece of work,for example, that indicated at m in Fig. 2, is placed upon the tablewith its rear edge abutting against the guide 122 the front marginalportion of the work may overlie the front guide, in which event thefront guide is not effective to determine the line in which. thefasteners will be inserted. The work will progress from right to leftand its rear marginal portion will pass over the guard 11swithoutengaging the raceway or the fasteners therein. A slight manual effort issufficient to l'eep the rear edge of the work against the guide 122, thework-engaging surface of which is parallel to the lines'of feedingmovement of the punch. When, under the conditions last stated, the firstseries of fasteners has been inserted the work. may be returned to itsoriginal starting position for the purpose of inserting a. second row offasteners in another line. For this purpose the work may be shiftedslightly to the rear far enough to place the front edge of the workagainst the front guide 116. ln this case the rear marginal portion ofthe work will overlie the rear guide 122, `and the work will occupy theposition indicated convention ally at rc2. According to the width of thework shown, and the position of the front guide 116, the second row offasteners vill be inserted exactly midway between the front andv rearedges of the work, but the slots 120 in the front guide enable thelatter to .be adjusted toward and from the fastener inserting means sothat the second row may be inserted, if desired, elsewhere than exactlyin the longitudinal median line of the work. rlhe work may nowbeadvanced again from right to left to insert the second series offasteners, and in the event that a third row of fasteners is desired thework may be reversed end for `the first hole.

end and placed with its present rear edge against the rear guide so thatit will again )y the positi a indicated at ai. The wird row of fastenerswill, therefore, be inserted at the saine distance from the `rear ew eas the c. ice between the first row and the present ont ed Assuming thatthe second row i fastensis been inserted in a line other than thelongitudinal median line of the worin a fourth row of fasteners may beinserted by againreturning the work to its starting position vwith itsfront edge against the front guide according to the position indicatedat x2. y Y

The motions of the various instrument-ali-` ties occur substantiallyfollows. The

J eoot will be raised manually in opposition to the applied force of aspring` (not sh wn) preparatory to placing the work in the desiredstarting position for punching llfhen the presserfoot is released itsspring will depress it to clamp the work upon the table. Tae punchinitially occupies the position shown in Fig. 3 eX- ceoting' that 'it israised as shown by Fig. 1. fien the` machine is started, as bydepressing a Storti* g treadle to connect the shaft 26 with suitabledriving mechanism, thev punch descends to the position shown by Fig. 3,thereby spreading the strands of the fabric to form a hole for thereception of a tener. rlhe presserfoot then rises to free the work forfeeding and the punch carrier 30 nieves from right to left, the punchremaining in the work to impartfeeding movement thereto. i'yilhen thepunch arrives at a position in registration with the lower-.setting ymember the presserfoot descends to clamp the work upon the table, andthe punch and upper setting member remain stationary until an eyelet hasbeen inserted clenched. During the work feeding period the lower setrises far enough to insert the spindle 16 through the leading eyeletV inthe raceway, and the raceway is then retracted horizontally' tothe rearto leave the eyelet on the spindle and to clear the path for the lowersetting member. This condition of the parts is shown by Fig. 4. rlhelower setting member then continues upwardly to complete the 'settingmovement, the spindle lbeing depressed relatively to the lower settingmember by the point of the punch, as shown by 5, and the lower settingmember rises far enough to insert the barrelofthe eyelet through theworlr and to clench the barrel conjointly with the upper setting member.rihe setting members are then retracted in opposite directions, 'theraceway is advanced to place another eyelet in registration with thespindle 1G, and the carrier 30 is moved to the right to its initialposition preparatory to beginning a new cycle of operations.
